Hi guys,
I'm really perplexed by this one. I added the urlfetch fix and the
run_on_appengine but am not sure if I did it write. Without the
urlfetch fix it says that the port is not defined.
I am using the following code in GAE i get a 404 not found error:

If I do the same thing in native python with the client library it
works.
any ideas? I've changed the usernames and passwords in the pasted
code.
